Application led July 1,

Beit known lthat I, THOMAS H. KANE, a' citizen of the United States, anda resident of Youngstown, in the county of Mahoning and State of Ohio,have invented a new and useful Window-Frame, of which the following isaspecification.

f Thi invention'relates to metal frames-for windows,J particularly theconstruction. of the side bars of slidable sashes, and to theconstruction of thevertical'members 'or mullions between the sashes;audits object isto provide a strong construct1on which may be` readilybuilt up from standard rolled bars with the-aid of few and simple tools.

yThis invention consist-s in the combination of bars of novel crosssections united by novel bolts, together. with sash side bars of novelcross section.- J While not limited to sash constructed accordin .to theformer Patent No. 933,908 dated eptember 14, 1909, reference is made tothis patent for the details of a sash whichy is adapted for use withmy-present invention.

In. the accompanying drawings, Figure 1 is an loutside elevation ofsashes, andmullions embodying this invention. Fig. 2 is an enlargedview, of a portion of IFig'. 1 at the4 point A. Fig. 3 is a similar viewat the point B. Figs. 4, 6 and 7 are 'sections on the linesl44, 6 6, and7-7 of Fig. 1,

' respectively on a larger' scale. 5 shows an arrangement of threesashes in one frame. Fig. 8 is a plan and Fig. 9 an end View of the boltemployed in tli1s construction on a large scale. y

Similar reference characters refer to like parts throughout the severalviews'.

As in the former patent, the sashes may be built up with 'side' and endbars formed of special rolled vbars 1 of I beam pattern, having theirflanges 2 rolled down onto `the edges of the interior bars 3 and theguide bars 4. 'These latter have guide flanges 5 slidable betweenthebars forming the mullionsx. l

The structure shown in Figs. 1 and 4 is designed for upper and lowerslidable sashes, but the construction may be duplicated as desired, thatshown in Fig.v bei'ng designed for three slidable sashes. In Fig, 4, tworolled sections'are shown, the smaller being used three times. Thissection is Specificatien of'lietterrs Patent. ,-nPvatented Aug, 22,1911.

formed of a flat plate 6 having a low' central .rib 7. The othersectionlhasa flat plate 8 mit adjacent sashesto-pass each other as shownin the ligure. Holes 10 .in pairs are punched through the flat plates,one of each pair on either side of the central rib, preferably of theexact form of the cross'section such exactness lis not necessary, beingdesirable however to make a goodappearance.

The bolt is preferably formed by bending a bar-of steel, flat on oneside and curved to the desired circle onthe other, as shown in Figs. 8and 9, and threading the end. Or if desired, a slot may be cut into anordinary bolt. The bars are then assembled as indlcated in'Fig. 4 andthe bolts introduced, one side 11 extending lalong one side of all theribs 7 and 9. Anut 12 is then screwed on, drawingjall the bars' togetherintol a rigid structure of great stiffness. The heads 13 are preferablyon 'the' Weather side.

l The larger f bars arel machined at their ends by cutting away theplates 8, leaving tongues 14, which tongues extend into slot-s in thesill plates 15' and lintel plates 16. If

and lintel plates and between the outer plates 6. The guide flanges 5 onthe guide bars of 'up and down as' far as the outer edges of similarflanges 18 on auxiliary top and. bottom bars 19 of the sashes. As shownin Fig. 6, these flanges 1 8 extenddown within the angle bars and assistin making tight joints. The upper and lower ends of the flanges 5 ofthey guide, bars completeithe corners of the sashes.

By merely perforating the dat plates 6 and 8, little of the strength ofthe bars forno ing the mullions is lost pfor when considered as beamswith reference to stresses in lines parallel to the window, these holes`are near the neutral axes where the remaining metal is of amplestrength,v When considered with reference to wind pressures, the centralribs are entire from top to bottom and are not affected by theperforations .of the plates 6 and 8. It is therefore unnecessaryto rollstrength lost by perforating.

Fig. 6 were turned upside-down, it wouldv be a cross section on the line8-8'of Fig. 1.

Angle bars 17 may be secured to the'` sill the sashesare preferablyformed to extend t bars with additional metal to provide` and a high rib9 of suflcient height to perof the metal 'forming the bolts, althoughspace the plates to form guidey ways `for window sashes, and guideflanges on the` sides of the sashesl extending into the guideways of themullion.

2. In a mullion for guiding window sashes the combination of bars inpairs, one pair for each sash, lone `bar of each pair formed with av ribof sufficient height to space` the bars to form guide ways for' thesashes, and the bar of the pair which faces the adjacent pair having arib of suiiicient height to permit such guided sashes to pass eachother,

and bolts to unite the bars.

3. In a window construction, the combination with vertically slidablesashes, of upright n iullions comprising narrow vertical plates inpairs, one of the plates of each pair formed with a longitudinal spacingrib of such height that the adjaccntport-ions of the sashes mayv freelyslide between the plates, one of the plates of'adjacent pairs having anintegral longitudinal `rib of such height'that adjacent sashesmay passeach other, and means to holdthe plates forming the mullions rigidlyunited.

4. In a window construction, the combination with the sill and lintel,of a mullion between thesanle comprising narrow plates in pairs, one ofthe plates of each pair formed with a longitudinall spacing rib osuchheight that the adjacent flangev of a sash may freely slide between theplates,one lofthe plates of adjacent pairs having alongitud-4 nal rib ofsuch height that adjacent sashes may pass each other, means to hold theplates rigidly united, angle bars secured to the sill and lintel,flanges formedon the sides of the sashes `to slide between the plates ofthe mullion, and anges ony the bottom of the lower sash and the top ofthe upper sash to .move into sliding contactwith the angle bars on thelsill andlintel respectively. -v
